A buyer placing a first private-label supplement order in China usually asks the factory one question: is the plant approved by the Food and Drug Administration. It is the wrong question, and the confident answer that often comes back is the first warning sign. The United States Food and Drug Administration does not approve dietary supplements, and it does not approve the facilities that make them. What exists instead is a set of separate obligations, some carried by the manufacturer, some carried by you as the importer, and a shipment gets stopped when any one of them is missing.
This guide sets out which obligation sits with whom, what a Chinese contract manufacturer can and cannot demonstrate on paper, and what to confirm before a purchase order is released. It sits under the wider compliance checklist by market and assumes the general customs mechanics covered in how to import from China to the USA are already familiar.
Nobody Approves a Supplement Before It Is Sold
Under the Dietary Supplement Health and Education Act, dietary supplements are regulated as a category of food rather than as drugs. There is no premarket approval step for a finished supplement, and no agency issues an approval certificate for the product or the plant. Regulation works after the fact: the responsible party is expected to have complied with manufacturing, labelling and safety-reporting rules, and enforcement follows when they have not.
Two consequences matter commercially. First, any supplier describing its factory as approved or certified by the Food and Drug Administration is invoking something that does not exist, which tells you how carefully the rest of their documentation has been read. Second, because there is no gatekeeper, the verification burden lands on you. That is the same structural point made in China supplier verification, sharpened by the fact that food entries are screened at the border.
One premarket step does exist, and it is narrow. An ingredient not marketed in the United States before 15 October 1994 is treated as a new dietary ingredient and generally requires a notification to FDA in advance of marketing. If a formulation includes a botanical extract or a novel strain that the brand has not sold in the United States before, that question needs answering during formulation, not during customs clearance.
What the Manufacturer Has to Have
A Chinese plant producing food for the United States market carries two documented obligations that you can verify before you order.
Food facility registration. Facilities that manufacture, process, pack or hold food for consumption in the United States must register with FDA, and a foreign facility must designate a United States agent who can be contacted on its behalf. Registration is renewed on a two-year cycle, so a certificate covering an expired biennium tells you less than the buyer usually assumes. Ask for the registration number and the current renewal, not a screenshot of an old confirmation.
Chinese export filing. Separately, a producer exporting food out of China is filed with the customs authority, and the filing carries a scope naming the product categories it covers. This is a useful cross-check: if the filing does not name your dosage form, the plant is telling you something about its certified capability before any audit takes place.
Guangci Nutraceuticals, a Dongguan contract manufacturer on ChinaMakersHub, is a workable illustration of what a complete paper set looks like. Founded in 2014 in Fenggang, Dongguan, it holds U.S. FDA food facility registration No. 17267166330 with a designated United States agent, renewed biennially, and China export food producer filing 4400/11384 issued by Fenggang Customs covering tablet candy, gel candy, hard candy and solid beverage. It also holds ISO 9001:2015 and ISO 22000:2018 certificates issued by Zhongjian Certification Co., Ltd. under CNAS accreditation C007-M, valid to 7 October 2026. The plant runs as a pure OEM and ODM operation with no stock catalogue, so every programme is built to the buyer brief.
Note what that list does not include, because the omission is the instructive part. ISO 22000 is a food safety management system standard. It is not the United States dietary supplement current good manufacturing practice regulation, which is a separate instrument with its own requirements for identity testing, master manufacturing records and batch records. A plant can hold a valid ISO 22000 certificate and still not be operating a 21 CFR Part 111 quality system, and a plant can operate to Part 111 without holding any ISO certificate at all. Ask which of the two the manufacturer works to, and ask to see the record types the answer implies. The difference between these instruments is unpacked in ISO 22000, HACCP and GMP compared, and the wider certificate landscape in ISO certifications for China manufacturers explained.
What You Have to Have as the Importer
The obligations that most often surprise a first-time buyer are the ones that cannot be delegated to the factory. They attach to the importer of record and to the responsible party named on the label.
| Obligation | Who carries it | What it means in practice |
|---|---|---|
| Food facility registration | Manufacturer | Registration number plus a designated U.S. agent; renewed on a two-year cycle |
| Prior Notice of imported food | Importer or filing agent | Submitted to FDA before the shipment arrives; a missing filing holds the entry |
| Foreign Supplier Verification Program | Importer | Written programme, a qualified individual, hazard evaluation and documented supplier verification |
| Manufacturing controls | Manufacturer, evidenced to you | Batch records, identity testing of incoming ingredients, retained samples |
| Label content and claims | Responsible party on the label | Supplement Facts panel, U.S. address, claim wording and disclaimer |
| Serious adverse event reporting | Responsible party on the label | A working U.S. contact route for consumers, maintained after launch |
The Foreign Supplier Verification Program is the one to plan for early. It requires you to evaluate the supplier and to document verification activities proportionate to the hazards involved, which usually means an audit report, testing records, or both, held on file before the goods land rather than assembled after a question is asked. That is a procurement task with a lead time, and it is a strong argument for commissioning an audit during supplier selection instead of after the deposit clears. Which audit type actually proves what is set out in China factory audits: which type you need.
Requesting the underlying paperwork at the quotation stage, rather than at the pro forma invoice stage, keeps this cheap. The general document set is listed in documents to request from a Chinese supplier before ordering; for supplements, add the facility registration number, the export filing scope, the certificate scope statements, and a sample batch record with commercial data redacted.
The Label Is a Regulatory Document
A supplement label carries required elements that a design studio will not supply on its own. The Supplement Facts panel has a prescribed format, the product needs a statement of identity and a net quantity declaration, and the name and place of business of the manufacturer, packer or distributor must appear. A domestic address or telephone number must be available so that consumers can report serious adverse events, which means the brand needs a functioning United States contact route from launch.
Claim wording is where the commercial risk concentrates. Statements describing an effect on the structure or function of the body are permitted and must carry the standard disclaimer that the statement has not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure or prevent any disease. Statements that a product treats or prevents a disease move it out of the supplement category entirely. A Chinese contract manufacturer will print the artwork you supply; it will not review your claims, and no reputable one will pretend to. Sign the claim set off with United States regulatory counsel before plates are cut, because a plate charge is cheaper to repeat than a recall.
Classification, Duty and the Entry Itself
Dosage form drives tariff classification, and classification drives both duty and which agency looks at the entry. A gummy presented as a confectionery and a gummy presented as a dietary supplement can fall under different headings, and powders, tablets and effervescent formats each have their own logic. Guangci lists HS 1704900000 for its gel candy and treats other dosage forms as to be confirmed per product specification, which is the honest position: classification follows the goods, not the marketing.
Get the classification confirmed by a licensed customs broker against the finished specification, and consider a binding ruling where a programme is large enough to justify one. Duty rates and any additional tariff measures should be checked against current published rates at quote time rather than carried forward from a previous order; the mechanics are covered in China import duties and tariffs, and folding the result into a real unit cost is set out in how to calculate landed cost from China. Who pays what at each stage depends on the Incoterm you agree, which is worth settling before the first quotation rather than after, as Incoterms for China explains.
Sequencing an Order So Compliance Does Not Become the Bottleneck
The pattern that works puts verification before commitment. Confirm the facility registration and the export filing scope, then read the certificate scope lines to check they cover your dosage form, then commission or obtain an audit that will support your verification programme, then freeze formulation and artwork with counsel signed off, then place the order. Pre-shipment inspection is booked as a separate step against agreed acceptance criteria, as described in pre-shipment inspection in China.
The commercial model matters here too, because it decides who owns the formula and who therefore carries the regulatory record. A white-label purchase of an existing formulation and a bespoke development programme place responsibility very differently, a distinction drawn out in private label vs white label vs OEM and in the wider private label manufacturing guide. Baseline import requirements outside the supplement-specific rules are summarised in the China import compliance requirements guide.
Regulatory scope and enforcement priorities change. Treat everything above as the structure of the problem rather than as current legal advice, and confirm the detail with the destination authority and with counsel qualified in the United States before you commit to a programme.
Common questions
Does the FDA approve Chinese supplement factories?
The Food and Drug Administration does not approve dietary supplement factories in China or anywhere else, because no approval scheme exists for supplements or for the facilities that make them. What a foreign plant can hold is a food facility registration with a designated United States agent, renewed on a two-year cycle. A supplier presenting that registration as an approval or a certification has misread its own paperwork.
Who is responsible for Foreign Supplier Verification, the factory or the importer?
The importer carries the Foreign Supplier Verification Program obligation, not the Chinese manufacturer. You are expected to have a written programme, a qualified individual, an evaluation of the supplier and hazards, and documented verification activities such as audit reports or testing records held on file. The factory supplies evidence into that programme; it cannot hold the programme for you.
Does an ISO 22000 certificate mean a supplement factory meets United States GMP?
An ISO 22000 certificate does not demonstrate compliance with United States dietary supplement manufacturing rules. ISO 22000 is a food safety management system standard, while the United States current good manufacturing practice regulation for dietary supplements is a separate instrument with its own requirements for ingredient identity testing, master manufacturing records and batch records. A plant may hold one, both or neither, so ask specifically which framework the quality system is built to and ask to see the corresponding records.
What documents should be requested before placing a first supplement order in China?
Request the business licence, the food facility registration number with its current renewal, the Chinese export food producer filing and its product scope, any ISO or scheme certificates with the full scope statement and validity dates, and a redacted sample batch record. Read the scope lines rather than the certificate headline, because scope is where the surprises usually sit.
Can the factory write the label claims?
A contract manufacturer prints the artwork supplied to it and is not a substitute for regulatory review of your claims. Structure and function statements require the standard disclaimer, and disease claims move a product out of the supplement category altogether. Have the claim set reviewed by United States regulatory counsel before printing plates are made.
